Parkinson's Disease (PD) is a neurodegenerative disorder that is frequently correlated with vowel articulation difficulties. The phonation problem arises in patients affected by PD is commonly known as Parkinsonian Dysarthria and identifiedby vocal signal analysis. The analysis supporte physicians and specialists in early detection and monitoring of dysarthria aiming, to increase patients life quality and to evaluate the efficacy of treatments. We investigate on vocal signal analysis correlation with speech patterns related to PD. Vowel parameters are considered as discriminant elements among PD patients and healthy subjects. Aim of this work is to define possible indicators for dysarthria in PD patients.

Abstract
Parkinson's Disease (PD) is a neurodegenerative disorder that is frequently correlated with vowel articulation difficulties. The phonation problem arises in patients affected by PD is commonly known as Parkinsonian Dysarthria and identifiedby vocal signal analysis. The analysis supporte physicians and specialists in early detection and monitoring of dysarthria aiming, to increase patients life quality and to evaluate the efficacy of treatments. We investigate on vocal signal analysis correlation with speech patterns related to PD. Vowel parameters are considered as discriminant elements among PD patients and healthy subjects. Aim of this work is to define possible indicators for dysarthria in PD patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
